Ying Zijin narrowed her eyes slightly, "So you took Alchemical Medicine?"
Sinai looked down and was silent for a moment, "Yes, which is why I can't return to my normal age and body to this day. This Alchemical Medicine has fixed both my age and body shape."
Ying Zijin's eyes flickered slightly.
She now knew where Earth's alchemy came from.
It was obviously introduced from the City of the World.
Because the Alchemical Medicine that Sinai mentioned is not available in the Alchemy world at the moment.
Aside from reducing the body size and reverting to youth, wouldn't this medicine allow one to achieve eternal life?
Moreover, the explosion in University Town was caused by an Alchemical Bomb they had never seen before.
Ying Zijin thought for a moment, "Do the residents of the City of the World often come to Earth?"
"No, ninety-nine percent of people would never come," Sinai shrugged her shoulders, "The science you are developing now is what we have already experienced."
